Re: XPS 8930, another CPU fan question?

@GKDesigns your pictures didn't show up for some reason, but I've been keeping an eye on this for curiosity's sake. This morning after an hour of gaming my CPU got as hot as 87 C, and averaged closer to 70 C. I don't think that things are quite as bad as I had originally thought.

However I've already ordered two 120 mm fans to go in the case, they should be here hopefully tomorrow. I can't find the correct bracket to attach it to the top of the case anywhere online, so it looks like I'll head into the metal shop and make something - that's the joy of being attached to a school when there's no-one else around. Access to many tools and light scrap steel. I'm sure I can bodge something together to make it fit. πŸ˜ƒ

Re: XPS 8930, another CPU fan question?

@savvy2  in my case, the computer being in a basement in the middle of the bald frozen prairies of Canada, room temperature isn't much of a concern. House is 22 C (70 F) upstairs, and cooler down here.

The computer is relatively new, so a gunked up cooler isn't a problem, and there are no wires causing the fan to not spin. 

You're 100% correct on the bad/missing case fans. There is only one in the case at the moment, and it's undersized. At the recommendation of others on this forum, I've ordered a pair of 120 MM fans. One to replace the 92 MM top fan and one to add in the front to draw in cooler air. I've also removed the excess drive bays, as they weren't being used and would cause air flow restrictions once I get the new fans in place.

As for the thermal paste, I'm not likely to remove the CPU cooler and replace the paste, unless I'm replacing the CPU cooler entirely. And depending on what happens with the case fans, I may or may not do that.

But thank you for your reply, it's all good informatio!

@SaveMeJeebus 

Images show up once the forum moderator approves them.  Dell has a social media conscience, if not adequate cooling on their XPS Tower product.

The sheet metal mounting plate for the top case fan is thin and easily bent, much like the lower HDD cages.  I don't mind the use of marginal material, but you do need to handle it with due respect.

You may not be able to copy it, material and mounting-wise.  So you may need to improvise with your own material.  I suppose you could modify the existing 92mm mounting plate, if careful not to destroy the flimsy thing, but that would burn that bridge.

I don't recall if it's possible to mount the fan directly to four holes in the chassis framework like I was able to do for the lower front case fan.  And I'm too lazy to look now.  Let us know how you get by on your own... others may need your solution... consider that a spec... others need to be able to reproduce it... that's why I went with four drill holes on the lower fan vs buying the fixture that won't be sold for very long.

Re: XPS 8930, another CPU fan question?

@GKDesigns I don't think that's it's possible to add the top fan directly to the case without drilling holes. I had the computer apart yesterday for the kids and I to look over and I'm pretty sure I'd have to drill holes to make it fit. Which isn't the end of the world either, I suppose?

Also, I've had a quick look around the interwebs and I'm surprised there's not templates for 3D printed versions of these items. Not too shocked, I guess, as Dell would likely squish them for copyright, but... a bit shocked anyhow. You can 3D print anything these days! If I was more comfortable with the software I'd just make one myself...

Drill away.  And know that one tiny rogue metal shaving can end it.

3D printing?  That's mad skills but doesn't meet the 'by anyone' spec! πŸ™‚

Aurora Top Exhaust Fan Bracket 


Just an FYI that the attachment points on both ends of the fan bracket for the R7/8 is configured differently from what is linked above for the R5 / XPS 8910.  This is what it looks like now (I believe the XPS 8930 shares the same internal metal frame as the R7/8).  In the R7/8 fan bracket, there is a single attachment point up top: one square hole in the center.  In the R5 photo, top, it has a double attachment point: two square holes, one on either end.  The bottom attachment is different too.  See photo. Not sure if this changes anything as far as compatibility, but just FYI something to look into if you're going to go this route. 

Another aside, the stock Dell fan is rated at 149 CFM for the R7/8 (the one in the link is 123 CFM).

Re: XPS 8930, another CPU fan question?

OP should seek out the top case 120mm fan mounting plate that looks most like the 92mm one currently installed.  Or devise his own mounting.

@r72019  (I believe the XPS 8930 shares the same internal metal frame as the R7/8).

It does, except for the 'hat' where the liquid cooling fan and rad are located. It looks like the pic you posted would work for XPS 8930. You might have to drill a hole, but better drilling the bracket in the garage than the case on your desk.

Re: XPS 8930, another CPU fan question?

@Dell630i I appreciate the listing, but the problem that I have with that is that it's nearly $70 Canadian dollary-doos (after shipping and exchange, NOT counting any duty that may apply)... and I'd have to wait for it to get here!

I've done a fair bit of metal fab in my life, and I do have the tools at my disposal in the school's metal shop, so I'm confident I can make something work. And barring that, I have a roll of double sided Gorilla Tape that would likely work in a pinch! πŸ˜ƒ
